Does anyone know where I can get a key blank for a TL Magna? I have only one key and would hate to lose it. Thanks.

You can get a blank from Mitsubishi spare parts and take it to a locksmith to cut and code (Mitsubishi no longer offers a pre-cut and coded key).
Or, I think Mister Minit also does keys for them, along with cutting and coding.

Thanks Ammerty, I can get the key cut and coded through my mechanic. Good to hear Mitsubishi still do the blanks, will chase it up.

Thanks Shezza

Turns out that is the wrong key for the TL, need one that is ID46 code, though all sorted for $110 including programming and cutting the key.

I dont understand how people advertise something without being perfectly certain they are advertising it correctly... They havent even corrected it. Glad you got it sorted anyway!
